For the\nLALInference.fits.gz,0 sky map, the 90% credible region is 1850 deg2.\nMarginalized over the whole sky, the a posteriori luminosity distance\nestimate is 2518 +/- 679 Mpc (a posteriori mean +/- standard\ndeviation).\n\nFor further information about analysis methodology and the contents of\nthis alert, refer to the LIGO/Virgo Public Alerts User Guide\n<https://emfollow.docs.ligo.org/userguide/>.",
